| Abstract: | In order to enable the textile and the users to avoid microbial disoperation,sixteen/eighteen tertiary amines andγ-chloropropyl trimethoxy siloxane are adopted to prepare antibac-terial agent GD-2 and then antibiotic finish is performed on pure cotton fabrics.The technology of synthesis and application are also studied.The optimal synthesis technology is as follows:six-teen/eighteen tertiary amines∶γ-chloropropyl trimethoxy siloxane∶ethyl alcohol=1∶1.1∶2,at 80℃ for 36h.And the appropriate application technology conditions are:usage amount of GD-2 is 20g/L,pH=6,pre-baking and baking temperature are 80℃ and 120℃,respectively. Antibacterial rate towards Escherichia coli and Staphylococcus aureus are 99.74% and 99.37%,respectively. |
